Morphological variability among specimens from two sources of error for morphogeometric data: within-observer (within-obs. 1, within-obs. 2), and among-observers (among-obs,), compared to among-genus variability. (a) Distribution of pairwise Procrustes distances among specimens within each group. (b) Morphospace for measurement error for specimens within each group.
